Heat oil in a large skillet over medium-high heat. Add the onion, jalapeño, and garlic, and sauté 2 minutes. Stir in squash and zucchini, and sauté 2 minutes. Add corn, beans, tomatoes, and thyme; cover, reduce heat, and simmer 10 minutes. Discard thyme; sprinkle with cheese. Serve over rice.
this is good, easy summer meal. I serve over quinoa or brown rice. Sometimes i add some diced avocado as a garnish. Also I add fresh oregano instead of thyme, sprinkle of cilantro, hot sauce, etc...
